METALLIC SLIDE FOR EXTENSION TABLES.

Application filed January 19, 1922. Serial No. 530,384.

To all whom it may concern Be it known that I, CHARLES T. SornL- LING, a citizen of the United States, residing at State College, in the county of Center and State of Pennsylvania, have invented certain new and useful Improvements in Metallic Slides for Extension Tables, of which the following is a specification.

This invention relates to extension tables and more particularly to the slides thereof and the primary object of the invention is to provide a novel extension table'slide in which the units thereof are all stamped or pressed from sheet metal, each unit being so formed that the same can be made from a single rectangular sheet of metal, thereby obviating the necessity of riveting or otherwise fastening pieces together as now contemplated in metal slides heretobefore patented.

A further object of the invention is the provision of a slide'for extension tables having the units thereof so shaped as to combine .with one another in such a manner as to permit free longitudinal sliding movement thereof but to absolutely preclude any lateral movement thereof, thereby providing a strong and rigid structure.

' A still further object of the invention is the provision of a novel metallic table slide embodying a number of units which can be readily or quickly separated to permit more or less units to be added thereto or taken away therefrom according to the desired length to which the table is to be extended.

lVith these and other objects in view, the

invention consists in the novel construction, arrangement and formation of parts, as will be hereinafter more specifically described, claimed and illustrated in the accompanying drawings, forming a part of this specification, in which drawings: I Figure 1 is a bottom plan view of a table top showing the improved slides associated therewith the table being in its extended position.

Figure 2 is a similar view with the table in its closed position and the slides in their collapsed position. I

Figure3 is a fragmentary transverse sectional view through the table top and slides.

Figure 4 is a fragmentary detail perspective View of one end of one of the end units of the slides; the unit being shown in inverted position. a

Figure 5 is a detail perspective view of one end of one of the intermediate units of the novel slide, the unit being shown also in an inverted position.

Figure 6 is a perspective view of one end of the other companion end unit the unit beipg also shown in an inverted position, ant

Figure 7 is a detail perspective view of one of the units of the slide showing the novel stop carried thereby.

Referring to the drawings in detail, wherein similar reference characters designate corresponding parts throughout the several views, the letter A indicates an extension gable; and B and C, the novel slides there- The table A can be of the usual or any preferred type and therefore a description thereof is deemed unnecessary. As shown, however, the same includes the two top pieces 10 and 11, the central pedestal or leg 12 and the bridge piece 13 carried thereby.

The slides B and G are constructed identically the same and therefore a description of one is suflicient for both.

Each of the slides B and C include end units 15 and 16 and intermediate units 17, 18 and 19. As shown the slides each include five units, but it is to be understood however, that more or less units can be readily added thereto or taken therefrom. The end units 15 and 16 are formed substantially the same, while the intermediate units 17, 18 and 19 are constructed identically the same. and all of the units are so formed and constructed that the same can be cut and stamped from a single sheet of metal as will be hereinafter more fully apparent as the description proceeds.

Each of the end sections 15 and 16 include an attaching base 20, which has one longitudinal edge turned in abutting relation therewith as at 21 to provide a reinforcement therefor. The opposite longitudinal edge of the base 20 of the section 10 is bent outwardly into a substantially U-shaped form, to provide a guide or rail 22, while the corresponding portion of the bar 20 of the unit 15 is turned inwardly to provide the guide or rail 22. The metal is then again bent back in parallel relation to the walls of the U-shaped guides or tracks 22 and 22 at right angles to the attaching bases 21 to provide guide walls 23. The guide walls 23 of the unit 16 has its lower or free edge bent back upon itself as at 24 to provide a reinforcement for the guide .be hereinafter more fully described while the guide wall23. of the unit (-15 vhas its, vlower or free edge bent back to providea guide or ra1l 24. The attachlngcbasestofxeach of-- the units 15 and 16 are secured by suitable fastening elements 25 to the lOWG1i= sur.-. face of the table top sections 10 and 11 and it can:-be see1r=tl1at theseun-its 15 and16 extend inwardly from the i-nneredg'es of-the table top sections The intermediateunits 17', 18 and 19 are each constructed from a single sheet ofrectangular metal and are all constructed subs stantially the same and are of approximately the Same size-as-the'end :units 15 and 16. As clearly shown in Figures 8 and 5 of the drawings; the: intermediate units 17;- 18 and 19' are -o'l' substantially inverted U-sha-ped form and include: a base orric'onnecting portion v "SOZaand depending side:' walls1- 31' "and 325- In theforming ofthe. side walls 31 a'nd 32, the same are bent adjacent to the connectin g'ibase -30 to form-vguidesor =tracks 33i 'and- -34,andnit :cannbe: seem that these tracks are disposed-in opposite il'eltltlOnxall-d are substantially- U-shapedwin crossfsecti'on. The-- outer! or lower longitudinal 1 edge-tof thenside or guide wall 31' is bent'backri-ipon itself to provide :a reinforcing. rib :01: an enlarged bearing nfacc. 35,; while: the? lower or outer edge of the guide wall 32' is bent back 3 to :prov-ide' a guide: @track 36* which is of substantially U-shaped form-:in cross section; It canbe seen: that the tracks r36? and 33 are disposed in opposite relation-t0 each other and in verticalwali'gnment. .The :unit

16 hasits' i-nner edge"providedz-with a cutoutportion- 37; while the: outer: edge of the unit l5 ha's=its edge:provided witlr a cut out portion 88 and the metal-1 therefrom bent back 'to provide a stop lug 391-5.

The units '17, 18'z'andw19 have thekinner edges: of the guide walls 31 and 32 provided respectively with a cut-out portion ,404' and a stop lug 41. This stoplugn tl is struck-out from the walls 32 015' each of ithearlastcimentioned unitsrs The unit 16 haslstruckvifronr-thet guide wall 23 thereof a right angular-lye extending lug 42 wl1icl1- adjustablysupportsma .stop 43; I This stop 2 43 "as shown, is -inEtl1e;:-na.turc of'a set-screw, so was to" permit the" same to i be readily-grieved: .out of thempatlr'ofwthe StOP'lllgS WhlClll will now be describedr- Tlle stopl ugs which engage thc -stop 43 arexindicated bythe numeral=44 and are disposed ina vertical r plane 1 and struck outwardly from the guide ltracks-36i-of ieach zof ethe intermediate units :17; l8tandil9l .Th'erunit 15 is also 'provided with a stopi44aadjacent to itsrinner end,-iwhich is disposed iniithe path of'the adjustable 'stop 45 carried by the 7 struckbut supporting plate elm-which is carriedby: the guide wall31of the section 17. The-adjustable stop 45 in the plate 46 corresponds to the adjustable stop 43 and the plate 42 iandeach of the: sections 17, 18 and 19 is provided with such 'a stop.

EachwseC-tiom 18 of:the slides B and C carries a block 50 which may be secured to the I. section: in any preferred manner, such as by screws or the like and these blocks 50 support the transversely extending bridge-block -13 whiclr carries the center leg or pedestal 12.

Now, it can be seen that the guide walls 31* of one of the intermediate sections is adapteclto slid-ably liti :in the a guidetracks and 365 so as -to slid-ably connect these units together and wall 31 of the section I 19 is adapted to slid ably L lit-:within the gu de tracks 22 and 24' nformed on the? end sec tion 15, while the guide :-tracks: 3,3 andi flof the section '19" 'are 'ad'aipted; to rslidablyieceive thew-guide wall' i23' 'of thexsections: v16, Byriwhi'eh arrangement; all 'ofthe units are slida blyn connected I together :and permittfree longitudinal movement ofztheasamenin rela- "tionuto wone vanotheriu It carter-her iseenerhowever; that broad guide :iwallscor faces 2 23;;31 andz32 of the :units will: absolrrtely preclude any lateral movementflofa the units-1 tin -,rela "'tion' to one another.
